PATENT OFFICE,

WINDOW-SHUTTER ATTACHMENT.

SPECIFICATION forming part of Letters Patent N 0. 790,732, dated May 23, 1905,

Application filed May 26, 1908- Renewed March 21, 1905. Serial No. 251.330.

My in vention relates to window attachments,

and more particularly to means for controlling the window-shutter or window-blind whereby the same may be readily opened to any desired extentand as quickly and efliciently closed.

My invention therefore consists of certain novel features of combination and construction of parts, the preferred form whereof will be hereinafter clearly set forth, and pointed out in the claim.

One object of my invention is to provide an attachment for devices used in opening or closing a window-blind from the inside of a building without raisingthe window-sash.

Other objects and advantages will be hereinafter made clearly apparent, reference being had to the accompanying drawings, which are made a partof this application, and in which Figure 1 is a perspective view of myinvention as applied to a pair of ordinary windowblinds. Fig. Qisasectiorial view ofa window,

taken on a line with the shaft controlling the shutters. Fig. 3 is a detail view showing, on a slightly-enlarged scale, the controlling means for opening and closing the shutters. Fig. 4: is a view of a part of the inside of a window frame or casing, showing the controllinghandle by which the actuating-shaft is rotated in either direction. Fig. 5 is a perspective de-' tail view of the housing.

In order to conveniently refer to the various parts of my invention and accessories deemed necessary to cooperate therewith, numerals will be employed, the same numeral referring to a similar part throughout the several views.

Referring to the numerals on the drawings, I indicates the window-frame of the usual conin place by suitable hinges 3 at their upper and lower ends, as clearly shown in Fig. 1. Each of the shutters is also provided, preferably near its lower end, with the bracket 4, secured in place in any desired way and carrying at its outer end the gear-wheel 5, designed to mesh with and be actuated by the worm 6 upon the outer end of the controlling-shaft 7, which latter passes through a suitable aperture provided in the frame-section Lsaid frame being,as is common, coincident with the thickness of the wall of abuilding. The inner end of the shaft 7 is provided with a controllinghandle 8, whereby the shaft may be freely r0 tated in either direction, and it is therefore obvious that the gear '5 is thus placed under the easy control of the person within the building, and since said gear is carried by the bracket I, attached rigidly to the shutter 2, the shutter may be easily turned upon its hinges, and thus brought into an open or closed position, as may be desired. A suitable stoppin 9 is also provided, which may be integrally formed with the plate 10 or indcpendentthereof, the location of said pin being such as will permit one complete revolution of the shaft 7, whereby the shutter may be brought entirely open or into a completely-closed position. Inasmuch as the shutters will be reliably held at any point, no other form of fasteners will be req uired-as, for instance, the common form of hook now usually placed upon the lower ends and inside of the window-blinds.

In addition to the two hinge-sections as above described I provide a keeper for preventing the separation of the hinges, a housing for the parts, and also bearings for the outer end of the shaft 7 and the upper end of the shaft of the gear-wheel 5, respectively. I accomplish this triple purpose or function by a single member 13, which consists of a flat top or horizontal portion 15, a body or vertical portion 14, and a depending end portion 16. The top portion is provided with an opening 17 to form a bearing for the upper end of the shaft of the worm-wheel 5, and the body portion and the depending portion are provided with registering openings 18 and 19, re-

struction provided with shutters 2, sustained l spectively, to form bearings for the outer end of the shaft 7 Directly below the opening 18 the body portion is cut away to form a shoulder 20, which is adapted to engage with the upper portion or leaf of the hinge and prevent the parts of the hinge from being accidentally separated, which would permit of the shutter falling. The main portion of the body is provided with openings 21, by means of which it is secured in position to perform its triple function of keeper, shield, and hearing. As the housing can be formed from a perforated plate which is bent into substantially an inverted-L shape it can be formed very cheaply, while it will add materially to the completed structure by preventing the separation of the worm-gearing as well as the parts of the hinge and affording a protection for the worm and its gear.

By the use of my invention it is apparent that a very cheap, safe, and efficient attachment is provided, and while I have shown and described the preferred form of the same I wish to comprehend such substantial equivalents and substitutes as may fairly fall within the scope and purview of my invention.

Believing that the advantages and manner of applying my invention to use have thus been made clearly apparent further description is deemed unnecessary.

What I claim as new, and desire to secure by Letters Patent, is

In a window attachment, two hinge-sections, the upper one of which is provided with a pintle and a worm-Wheel the pintle being rigidly secured to the wheel and to said section, and having its upper end projecting above the top of the wheel, an operating-shaft, the inner end of which is provided with a crank and the outer end with'a worm, and an inverted- L-shaped housing'consisting of a body portion, a top and a depending end portion, the top being perforated in alinement with the pintle and forming a bearing for the upper end thereof and the body portion and the end portion being provided with registering perforations, respectively, to form bearings for the end of the shaft, and the body portion directly below its perforation being cut away to form a shoulder in position to engage with the upper leaf of the hinge, and being further provided with openings for securing means.

In testimony whereof I affix my signature in presence of two witnesses.
